Yes. But first you must have a network
connection to "load" the desired sign. After it plays for at least
one cycle, your video files (not web pages or Google Slides) will be
cached (saved) and you can disconnect the network.

Can I use SignStick with WiFi network connection?

Yes but WiFi is often a problem for live video if
there is not enough bandwidth, for example if many others use the same
WiFi network at the same time. Wired network is often better.
